| Number of relay outputs | 2 |
| Relay Contact Ratings: at 30VDC at 125VAC |
2A 0.5A |
| Number of inputs | 2 |
| Quiescent current | 400 μA |

The module IOM22 ensures:
- Monitoring of status of the non-addressable fire alarms and other devices with voltage free output;
- Control of the external executive units.
An example of application of a device for controlling analog linear alarms connected to IOM22 via a four-wire scheme. So, each of the two alarm circuits of the module IOM22 monitors status of its linear alarm and de-energizes it in case of response by power circuit breakage.
Each relay output of IOM22 is adjusted independently and can be switched on or off by any system event.
